Controlling higher-order power converter topologies requires decoupling system states into isolated, sequential loops to prevent control interaction and guarantee stability. This technical note details the design, digital implementation, and tuning of a cascaded voltage control strategy applied to the DC bus of a step-up boost converter. The control topology structures a fast inner inductor current loop nested within a slower outer capacitor voltage regulation loop. The note provides detailed system-level plant modeling in the Laplace domain and addresses delays caused by zero-order hold (ZOH) hardware sensing and processing lag. The cascaded design is validated against hardware experiments, exhibiting disturbance rejection and reference tracking.
